Less expensive strobes that exhibit a color change at different power levels can create color problems that are difficult to correct.

If a setup uses more than one strobe, and they are all at the same power setting, and therefore the same color temperature, then any incorrect color can be globally corrected.

But...if the strobes are at different power settings..i.e. the fill light is at less power than the key light which in itself is at less power than the background light etc. then you have a situation with multiple color temperatures which is very difficult to correct.

If you're shooting professionally where specific product colors are important, such as food, fashion, catalog work, etc. it pays to invest in professional equipment with consistent color temperature at ALL power settings.
